ABSTRACT:
An apparatus for processing cassettes which contain exposed photographic roll films has an inclined chute the upper part of which receives successive loaded cassettes in predetermined orientation by way of a duct when a first turnable gate between the duct and the chute is held in open position. The first gate can seal an inlet opening at the upper end of an antechamber which is adjacent to the upper part of the chute and is dimensioned to receive one casette at a time. The outlet opening at the lower end of the antechamber can be sealed by a second turnable gate which, when moved to the open position (simultaneously with movement of the first gate to closed position or vice versa), allows a loaded cassette to descend onto a third turnable gate and to assume an optimum position for removal of exposed photographic film therefrom. When the third gate is moved to open position, it allows an empty cassette to pass through a conduit and into a collecting receptacle. The gates are mounted on a shaft which is rotatable back and forth by an electromagnet. At least the first and second gates are sector-shaped and overlap each other to such an extent that the first gate prevents penetration of light into the antechamber by way of the inlet opening when the second gate exposes at least a portion of the outlet opening of the antechamber, and vice versa. The films which are removed from cassettes resting on the third gate are spliced together to form an elongated web which is transported through a developing machine.
